Collateral

It’s been heads-down hard work around here ever since OOPSLA in October. Haven’t even filed my expense report yet. (Coding is more fun.) So I’m pretty late in posting that…

At OOPSLA, David Reed gave a keynote about TeaTime, the model of replicated objects and time that underlies our thinking on Croquet. The slides are available here.

While David Reed continues to work on the fundamental research, David Smith and Andreas Raab have developed a Simplified TeaTime that forms the basis for the first fully functioning Croquet release, codenamed Hedgehog. They presented this model at a workshop at OOPSLA, and their slides are available here. Be aware that there’s some different terminology between the two presentations. For example, party and veil can roughly correspond to island and farRef. No release date yet – the whole process is what David Reed calls “invention in public”, so I’m not sure what a “release” should really have. But I can say that there is working code already.

Also in October, Julian Lombardi led a demonstration of Jasmine Croquet to a general audience in Madison. The video is here. A month earlier, Julian gave a report of our work in collaboration with the Japanese NICT. The slides from that, including video-capture, is packaged here.

Finally, there’s some very old documentation of the earliest version of Croquet here. The appendix includes a somewhat mis-edited version of an essay by Alan Kay, entitled “Is ‘Software Engineering’ an Oxymoron?”

  1. When is the next scheduled presentation by any of you Croquet guys at a conference or public lecture? Anything in the Boston or San Francisco areas on the horizon?

  2. Everyone will be at C5 in Berkeley, Jan 26,27. http://www.db.soc.i.kyoto-u

    Two days later, a bunch of us involved in education will be at Educause. Alan Kay will give a plenary presentation. http://www.educause.edu/eli061 There will also be a membership meeting for the new Croquet Consortium.

    Oh, and I forgot: Julian and David Reed just got back from a well-received plenary presentation at Sloan-C in Orlando. http://www.aln.ucf.edu/
